In this lyrical exploration of life, loss, and survival, Meera Subramanian travels in search of the ordinary people and microenterprises determined to revive India’s ravaged natural world: an engineer-turned-farmer brings organic food to Indian plates; villagers resuscitate a river run dry; cook stove designers persist on the quest for a smokeless fire; biologists bring vultures back from the brink of extinction; and in Bihar, one of India’s most impoverished states, a bold young woman teaches adolescents the fundamentals of sexual health. While investigating these five environmental challenges, Subramanian discovers the stories that renew hope for a nation with the potential to lead India and the planet into a sustainable and prosperous future.
